Prona, if you sell it ebay or another way; PM me or something, I'd def. be interested. I'd love to try the 2.0 but I just don't have that kind of cash to drop.

Mr. K6 ok I'm now confused .. I had a 1.7 cpu and was following the setup from sticky Photo Guide for Pin Modding and the image provided shows the short horizontally:

From the Photo Guide


Now in your setup its showing the short vertically.



Which way does it go?? I was following the guide and placing the short in horizontally and (of course.. now) it was not working! I've got a new 1.7 coming and should be here tuesday next. Which is correct and shouldn't 1 photo or the other be corrected?

Just to update, I've been running this at 2.4 for the last 5 hours while priming and gaming, no issues what so ever. Current voltage is 1.372, I could probably go lower, but prime temps are only 57, gaming temps more like 55, and I like the extra buffer.

2.0->2.66 will take alot of luck, but it is possible. The problem here is the limit of the architecture, and if you find a damn good chip, it could be possible. Temp-wise, anything over 1.5v and you're going to start hitting 65C with a good AS5 job, so the 1.6v I've seen the others get by on wont cut it, especially on that poor battery .

I got my Dothan 745 for $160 shipped, buy second hand from a desktop user so you know what you're getting (or from prona if he does sell )

Adrenolin, both of those pictures are oriented in the same way. VSS is ground, and it doesnt matter which ground you use. What does matter is that you're grounding the BSEL[0] pin. Look at the chart carefully and you'll see that either method does it. If you want to know, I do it horizontally, better chi .

Anyway, if you have any questions about specific voltages or pins, lemme know!

EDIT: Another update , started using I9KFanGUI and the CPU doesnt get above 50C while priming, and that's on the "slow" fan speed setting. Yay

Wow, looks like you got a very nice processor, Mr. K6! Mine needs 1.436 to be 100% stable at 2.4. I get max load of 61F or so.

EDIT: BTW, I did grounded VID1 and VID2 so that it would boot up at 1.436 and remain there without the need for a software voltage moderator (like rmclock or chc). Also, with this, I have more availability as to the number of lower voltage settings I can select (if I am using Automatic Management in RMClock) to compliment the intermediate speedstep multipliers. Basically, I can select any voltage under 1.34 with 0's for VID1 and VID2. Also, the lowest voltage I can select by grounding VID1 and VID2 is 0.796, which'll give you pretty good battery life .

Hmmm... good way of doing it. I just ground VID3 because it essentially gives you any voltage step from .700v to 1.452v. Keep posting this kind of stuff though, the more ideas and techiniques we get up here the better

As my 1.8 was a stellar chip and ran 2.4@ just 1.276v, my next project, a 2.0 will probably be not so lucky. So I am darn glad to see a confirmed voltage mod on one of these things!

p.s. for best OC succes, get a new cpu, the newer the better... worked for me.

Actually with VID3 grounded, if you look at the voltage table, anything with a VID3 = 1 isn't accessible. Also, if you take another look, if you ground only VID3, you actually will boot at default stock voltage (because voltage of 1.340 and 1.356 already have 0's for VID3). In your scenario, you might not notice the unstability during bootup (i.e. it gets you through). However, I wouldnt rely on a VID3 simply because if you reinstalling an OS or doing anywork outside the control of software voltage moderators, you run the risk of instability.

Read above in my original post. If it is grounded, and you call for it to be grounded (a 1), it'll reverse itself. I dunno why it does that, but it works. For instance, the 1.260v that I call for in software is actually 1.372v, and if I go down to 1.212v, I get the same 15min prime error that I do at 1.340v (obviously). That's why VID3 is the sweet spot if you're going for a nice voltage boost. If you want to get some insane voltage, ground VID 4.

I think you are misunderstanding what I'm trying to say. The 1.8 boots up at a default voltage of 1.340v. Take a look at the voltage table for 1.340. It's 0 1 0 1 1 1. Okay so your VID3 is grounded and forcing a 0. That's great and all, but considering the fact that the cpu defaults to a value of 1.340 at bootup, vid3 is already at 0 for that value. Thus you still get 1.340.

I'm so confused and I really want to understand this stuff. If your stock voltage is 1.34 (010111) and I grounded vid3 it would reverse (011111) and my voltage would be 1.212? right?

No, it wouldn't do anything. Grounding VID3 forces a value of 0. It doesn't reverse the value.

hmmm... ok, I see what you mean prona. And yah, that's how it works. I dont think I'd be able to boot at any lower voltage. You're saying that VID3 grounded forces a value of 0 nonstop, and that would explain the voltages I'm getting. So then, the CPU still boots at 1.340v, which is damn beneficial in this case. However, that doesn't explain why I get such low temps at .828v, which I thought should be .700v, I'm going to do some testing on the other end and get back to you guys.

My experience to date -
1.7 - tried 2 - both worked
1.8 - tried 3 - no go on all 3

Yea, that makes sense to me too. So the only vids you can really alter are 0,1,2 and 4.

Did you try the volt mods on those 3 745s?

You can alter any of them VID0 through VID5. I altered VID3 and that's what'd been doing it for me. You get a great selection of high range (1.340v->1.452v) and low range too.

hmmmm

well i just ordered a 1.6 yesterday for $122 CAD w/shipping and a 1.8 for $197CAD w/ shipping today(cuz it was such a good deal, and now im gonna sell the cheap 1.6 for more heh), so what u guys are all talking about is the fact that the horizontal pin mod wont cut it. Im gonna need to "ground something else" when u say ground VID3 (or whatever number) what does that mean, jumping a wire from that hole to which hole on the socket??

and since its kinda going back and forth here, what is the best VID to ground to give me the best solution, im familiar with CHC and that already so I guess im just trying to figure out what VID to ground so that I can have good control over the voltages when I use CHC later on.

You guys rock , and thanks in advance.

If 1.340v is stable enough for you to boot in, I guess you could ground vid3. If not, try something like vid1-vid2. Download the specifications pdf file from intel's website and be creative

hmm, im not sure why, and im not sure id be able to understand why VID3 but I guess I can try it and see how it goes, What type of wire do I need to use, im gonna have to go to the hardware store I think...

thanks!

First one that burns out their CPU doing this I'm sending a toaster to! hahaha

(Have fun... I'll be no part of "extreme" anything with a laptop)
